While eSATA is one of the fastest interfaces, it is surpassed by both Thunderbolt (10 Gbps) and Thunderbolt 2.0 (20 Gbps), which are alternatives to eSATA. Why SATA is superior in video surveillance?
In video surveillance, just achieving the required storage capacity is not enough. Maintaining data integrity during transmission as well as error correction features is also needed. Parallel ATA drives deliver admirable operation in these tasks and now SATA drives are raising surveillance storage performance even higher.
